To all whom t 'may concern:

Be it known that I, HARRY J. Hnivnnroxs, a citizen of the United States, residing .at Sterling Station, in the county of Cayuga and State of New York, have invented certain new and useful Improvements in Lubricating Systems, of which the following is a specification.

This invention relates to lubricating systems especially adapted for use, on motor vehicles and has primarily for an object the provision of a system which automatically maintains the level of the lubricant m the engine base at a predetermined height.

Another object of the invention is to provide a simple and inexpensive device of this character'Y which is especially adapted for use on Ford cars, although of course the device is applicable for use with any type of engine using the Splash system of Vlubrication.

The above and other objects of this invention will be in part described and in part understood from the y:followfing description of the present preferred embodiment of the invention taken in connection with the accompanying drawings, wherein:r

Figure 1, is a side elevational view ofv a system constructed in accordance with my invention illustrating its application.

Fig. 2, is a vertical sectional view thereof showing parts removed.l t

Fig. 3, is a detail fragmentary sectional view of the device showing especially the valve arrangement for the filler cap, and

Fig. 4, is a detail fragmentary sectional view showing especially the regulating pocket. Y Y

In the drawings in order to illustrate the application of this invention a portion of a motor vehicle body 5 is shown, the end of the floor of which is inclined upwardly as indicated at 6 and has upstanding from the front end thereof a dash board 7.

The device of this invention consists especially of an oil supply tank 8, the upper face of which is preferably beveled to snugly engage the inclined portion 6 of the floor of the vehicle and has upstanding therefrom a supporting bar 9. TheJ said bar is bolted or otherwise secured to the dash board 7. As is` apparent the bar 9 is arranged on the top of the supply tank 8 and secured thereto in any desired manner.

The rear end of the tank has anapertured vsight 17.

extension 10 formed 'thereon through which the body bolt of the car may extend if desired. vThe tank 8 has a small reservoir 11 depending therefrom which is' preferably o f a cylindrical configuration and is'provided with a lateral outlet opening 12 which carries an outlet'conduit 13. The conduit 13 terminates in a regulatingfpocket 14, which latter is mounted in the base of an engine 15. The pocket 14 is preferably of a cylindrical configuration and terminates at its lower end in a cylindrical barrelrl, one end of the latter extending into the base of the enoine 15. The oil is in this way conveyed from the tank 8 through the conduit 13,V thence through the .pocket 14 and into the barrel 16 from which it passes into the engine as shown to advantage in Fig. 4. The regulating pocket 14 is suitably vented as shown in Fig. 4 of the drawings, whereby when the oil reaches the lower end of the conduit 13 within the pocket 14, communication will be closed through the conduit forming a partial vacuum in the latter. As soon Vhowever' as the level of the oil'lowers in the engine so as to uncover the lower end of the conduit, air will be permitted to pass through said conduit, thereby relieving the vacuum .and permitting the oil to pass fromv the supply tank into the regulating pocket until the lower end of the conduitY is again sealed by the oil.

In order to determine at all times the exact amount of lubricant in the tank 8, a suitable sight 17 is provided, which in this instance consists of a transparent tube which is in communication with the top of the supply tank l8 and extends upwardly through the floor of the vehicle directly infront of the dash board 7 as shown in Fig. 1. This tube may, of course, be covered with a suitable non-frangible material. A oatV 18 is mounted in the supply tank and has a rod 19 upstanding therefrom and extended into the sight 17 Any suitable ytype of indicating nger, such as that indicated at 20, Vmay be mounted upon'the upper end of the rod which will be visualized through the In order that the' vacuum will not be' broken when the Ysupply tank' 8 is being replenished,'a valve 21 is provided which is yieldingly mounted in the reservoir 11 and is adapted to automatically engage aV valveseat in said reservoir as soon as "the filler cap 22 of the supply tank is removed. The spring Which actuates the valve is suflicient to overcome the resistance of the liquid Y vehicles other than Ford cars, Without departing from the spirit of this invention. Moreover, various changes may be made by me in the details of construction, proportion and arrangement of parts Without departing from the invention as covered in the appended claim.

What is claimed is:

In combination with la vehicle engine havling a conventional lubricating base, a Vsupply tank, a lubricant conduit depending from said tank and into said vehicle engine base, and a Ventilating pocket including a cylindrical body one end of which passes through the Wall of the engine base and is engaged With the lubricatingconduit inside of the base, the opposite end of said cylindrical body issuing into a right angular cylindrical member outside of the base, one end of said right angular member extending into said engine base.

.In testimony whereof I alix my signature in presence of two Witnesses.V
